Wizard,
Yea, Back then Charlie was using bleach to clean up the pools, remember? In case you did not notice, at the cave it is a little deeper and hotter. That is because the hot spring down there is exerting pressure on the sand from there. I will bet money that when I hose it out that there will be, beer bottles, clothes, flash lights, batteries, and trash down there. The white stuff you refer to is methane. Which occurs when the alge breaks down. It causes a stinky smell. When I do clean it out I will leave a couple of feet of sand, OK.

I blame my grandmother for my overly sensative nose. I would fart in the bathtub upstairs from her and she would notice it, downstairs from the other side of the house. So it is in the genes. And if I did not punctuate correctly she would sound like one of those hell fire and brimstone preachers. Ya gotta luv em.
Does not Del Mar mean the ocean in espanol? And did you get my email?
Happy soaking ;~)
